Do all four if you're going to replace them, do bear in mind a leak-off test doesn't tell the whole story with injectors though. I doubt very much they are causing the starting issues though, how can they cause low rail pressure before they even fire...

The rear beam will almost certainly be knackered, when they go they usually develop a serious lean on the offside.

Did you try the battery trick?

Not yet mate but its been suggested that the jump start made the starter motor spin faster than normal therefore increasing pressure and making the engine fire, the 1st injector was pissing diesel out the top the other 3 were just trickling we tried to clamp the hoses but couldnt do it sufficiently to make the engine fire... i also now have developed a battery problem..... with all this trying to start the engine malarky, batt light keeps coming on randomly when driving car is currently off road until i get a new injector and back axle, not giving up though!
